There has been a few questions on how to use VB to connect to a mySql database. This will show you how to connect without using a DSN. Most of the code is from a ADO Tutorial from this site. I just modified it to show how to connect to a mySql Database.
A perfect example of using an Access database. With these example, you can add, delete, moving in the database. All validation is done. Use PageUp and PageDown to seek records. Very nice interface. Reusable code. All code is commented. Simply the best example ever on planet-source code about database management.
The prodram look just like Access, so don't be mistaken. IF you won to learn how to work with databases- the answer is Quarantine DB. The program uses ADO and DAO. With QuarantineDB you can work with, create, delete, rename tables and queries, add, delete, update records. You'll learn how to work with MDI form. Just try it and don't forget to VOTE FOR ME. e-mail : kicheto@goatrance.com
Backup and Restore your Outlook Address Books contacts. You can save your contacts as different profiles which means you can maintain different contact books and restore it whenever and wherever you want! Saves you considerable of time and resources since your address book is now intact and is stored in a Central repository. Ideal for a network environment with a central Database server(SQL Server, preferably).
Search data in a database depending of what you write in the textbox, if you press the "M" key in the textbox you will get all the data that begins with "M", VOTE FOR ME !!
Learn how to quickly attach a console to a window for instant output and feedback. Console apps trivialize the ability to output text data in a fast efficient manner. Displaying diagnostic data in a windowed application is not so trivial or straight forward. Have you ever wanted instantaneous feedback on a variable or state in your windowed program at run-time? One solution is to "attach" a console to your window. Through this attached console, your window can conveniently output information. The WinProg source below does just that. WinProg allocates a console window in WM_CREATE. It is through this console that WinProg can communicate what messages are being sent to it. The example below handles various messages in the window handler and then outputs them to the console. By retrieving a HANDLE from my CreateOutputConsole() function, you can then display whatever data you wish with a simple printf-like function - ConPrintf(). Just pass the HANDLE to the console, the size of the output buffer (big enough to accommodate the format string and the optional variables), the format string i.e.("Data: %d") etc...and the optional arguments (if any). Very similar to printf().
Version 1.0.13: added some error handlign. NEW! Added functionality: now it works also with password protected access databases. Update your new database from your old database at amazing speed. The program updates all the tables from the old database to the new one. If you find anything faster than this please let us know. Enjoy
This little bit of code and table will help you manage tables with linked/split databases. Currently it only handles MDB or Access databases, but it would be a simple task to set it up to handle other types of tables. Basically, with this little code, you can Import a table from another DB, Export and then LINK to data from Current db to another db, or Link to external data in another Db all automatically just by setting the tables in the MOVETABLES table. I'm also going to add some features that will allow you to "upgrade" an external data table with a new Structure for those of you who make a new front end and also change the structure of the back end but you don't have access to the production version of the back end for whatever reason. Should be up sometime today.
Using ADO: This is a demonstration of how one can take selected items at runtime from a user, create a parameter query using the selected items and then run the parameter query.
Create a CSV file (ie. for Excel(???)) based on a parsed ADO-Recordset - very cute :)
Take the advantage of learning ADODB and the datagrid control in a MdiForm with the capability of doing; addnew, delete, edit and search... Thanks for using ...
Thanks to Collin McAllister for the 7/13/1999 submission this is based on!! A visual adhoc query form that allows multiple criteria selections and simple joins. A simple (limited) somewhat user friendly way to create simple queries.
VB module to read and store ANY kind of picture file pictureboxes support into a database, it's easy and it's pretty fast... please, rate it, any comments are wellcome
My code is a way to password protect a cd, so that only a certain user can access the setup program, it also allows the user to choose which one of the cd drives its in.
Provides a simple to use, yet useful phonebook/contacts program. I have gone through and sussed out pretty much every bug I could think of, see if you can find any!
This was a piece of software i did for my HSC major assesment, 93% cheerin! Anyway, i have put a fair bit of work into it, it still has bugs, coz i only finished it the other day i haven't had a chance to fully de-bug it. There are also some changes I would like to make in the near future, but it is basically finish, so please enjoy, let me know what u think, and PLEASE vote high, i would love to win this months comp :-) The Admin Password and Teacher password are both "Gilroy"
PLEASE FIND A BUG!!!!!!!!!!!!!!!!!!!!!!! I DARE YA! I fixed the one that was found when you type somthign in the main interface when you have an empty dat file then click in the search list box. See if u can find more. By the way PLEASE VOTE!!!! thanx ;-) Well finally after heaps of emails complaining about the source safe protection HERE you go!! a non protected version, as you will see the code is a shocka, it really needs arrays. It reads everything off a text file to save HD Space. I am going to make an Access version prolly in about a month or so, well maybe longer coz i am doing my HSC. Anyway, this prog provides a simple to use, yet useful phonebook/contacts program. I have gone through and sussed out pretty much every bug I could think of, see if you can find any! I DARE YA TO FIND A BUG!!!!!!!!!!!!!!!!!!!!!!

With this application you can see how DAO works. You can completely control the database with this code, you learn how to read, insert and delete things from a database with no data controls or whatever :-) And also a great deal of the ListView control is used for this app. And it is completely documented and explained!!
Helps to maintain credit customers, with the details of bills and outstanding balance, etc. Useful for small companies, total solution. No need to purchase big software which has got too much unwanted functions for which you don't need to pay for. The code has got very useful stuff like managing ADO DB, creating reports, etc... hope you like the code and most of all the application. Most of the reported bugs are fixed (which were a few ui bugs). Check out now the update.
